Illustrated material. Figs 14 View FIGURE 14 C1–C3: syntype, Bad Vöslau ( Austria): SL: 55.5 mm, MD: 34.4 mm, NHMW 1849/0023/0005a, specimen illustrated in Hoernes & Auinger (1879, pl. 3, fig. 4); Figs 14 View FIGURE 14 D1–D3: syntype, Enzesfeld ( Austria): SL: 52.0 mm, MD: 31.0 mm, NHMW 1853/0010/0005; Fig. 3 U: syntype, Bad Vöslau ( Austria): SL: 42.8 mm, MD: 27.4 mm, NHMW 1849/0023/0005b.

Revised description. Medium-sized solid shells; low conical to weakly coeloconoid spire; spire whorls bulgy and convex, delicate spiral threads on early whorls, later smooth except for prominent growth lines, suture deeply channelled. Subsutural flexure shallow, moderately curved, moderately asymmetrical. Shoulder rounded, rarely subangulate, position of maximum diameter slightly below; last whorl only weakly ventricose or straight-sided, slightly constricted at base, typically with several strongly incised growth lines. Faint spiral cords on base; entire whorl covered with delicate spiral sculpture, visible only in tangential light. Siphonal canal short, slightly recurved; siphonal fasciole weakly swollen, twisted with prominent growth lines. Aperture moderately narrow, widening towards siphonal canal. Colour pattern consisting of numerous spirals (no subquadratic dots can be observed as illustrated by Hoernes & Auinger 1879).

Shell measurements and ratios. n = 10: largest specimen: SL: 61.8 mm, MD: 35.0 mm, mean SL: 50.2 mm (σ = 5.7), mean MD: 31.2 (σ = 2.8), spire angle: µ = 118.8° (σ = 4.7°), last whorl angle: µ = 38.9° (σ = 1.0°), LW: µ = 1.6 (σ = 0.08), RD: µ = 0.71 (σ = 0.03), PMD: µ = 0.87 (σ = 0.02), RSH: µ = 0.12 (σ = 0.01).

Discussion. Most shells which can be reliably identified as Kalloconus voeslauensis are characterised by several deeply incised growth lines on the last whorl. In their original description of this species, Hoernes & Auinger (1879) referred also to specimens from Lăpugiu de Sus, which, however, represent Kalloconus hungaricus . The specimen illustrated by Hörnes (1851, pl. 2, figs 5a–b) as Conus clavatus is an aberrant specimen of Kalloconus voeslauensis . Sacco (1893b) introduced ponderoclavata as varietal name for this aberrant specimen, which thus is a subjective junior synonym of Conus voeslauensis .

Paleoenvironment. The specimens from Bad Vöslau are filled with clay and might have dwelled in basinal settings. Mikulov-Kienberk and Enzesfeld, in contrast, represent shallow marine environments (own data).

Distribution in Paratethys. Badenian (middle Miocene): Alpine-Carpathian Foredeep: Grund ( Austria); Vienna Basin: Bad Vöslau, Gainfarn ( Austria), Mikulov-Kienberk ( Czech Republic) ( Hoernes & Auinger 1879); Eisenstadt-Sopron Basin: Forchtenau ( Austria) ( Sieber 1956); Transylvanian Basin: Lăpugiu de Sus ( Romania) ( Chira & Voia 2001); Pannonian Basin: Szob, Budapest, Mecsek Mountains ( Hungary) ( Csepreghy-Meznerics 1956; Strausz 1966).
